United StatesWhat I'm looking for
At CJ26 Logistics, I provide Tier 1–2 IT support for 100+ employees across Windows 10/11 and macOS, resolving account, endpoint, hardware, software, and connectivity issues.
I administer Microsoft 365 and Active Directory, manage ServiceNow incidents within SLA requirements, and troubleshoot recurring DNS, DHCP, VPN, and Wi-Fi problems to improve reliability.
I've also built cloud infrastructure for Second Chance Global across six sites using Microsoft 365, Entra ID, Intune, Autopilot, and UniFi. I'm building on hands-on home-lab work in servers, VLANs, SCCM/MCM, PXE imaging, AWS, identity, and networking as I move into systems administration and cloud security.
